THE THREE SIDES OF A TRIANGULAR LOT

just olya [345]

Answer:

259.09 feet

Step-by-step explanation:

Given that,

The three sides of a triangular lot are measured to be 100.52 ft, 15.321 ft and 143.250 ft.

We need to find the perimeter of the lot.

We know that,

Perimeter = sum of all sides

P = 100.52 + 15.321 + 143.250

P = 259.09 feet

So, the required perimeter of the lot is 259.09 feet.

Step-by-step explanation:

Part A: $u^6$ can be written as the square of u³, or $(u^3)^2$ . Similarly, $v^6=(v^3)^2$ . Hence, we can write this as a difference of two squares by writing it as

$(u^3)^2-(v^3)^2$

Part B:

<h3>Difference of Two Squares</h3>

<u>We can first factor a difference of two squares a² - b² into </u><u>(a+b)(a-b)</u>. Here, <em>a</em> would be u³ and <em>b</em> would be v³.

$(u^3+v^3)(u^3-v^3)$

<h3>Sum and Difference of Two Cubes</h3>

We can factor this further by the use of two special formulas to factor a sum of two cubes and a difference of two cubes. These formulas are as follows:

$a^3+b^3=(a+b)(a^2-ab+b^2)\\a^3-b^3=(a-b)(a^2+ab+b^2)$

Since u³ + v³ is a sum of two cubes, let's rewrite it.

$u^3+v^3=(u+v)(u^2-uv+v^2)$

Since u³ - v³ is a difference of two cubes, we can rewrite it as well.

$u^3-v^3=(u-v)(u^2+uv+v^2)$

Now, let's multiply them together again to get the final factored form.

$u^6-v^6=(u+v)(u^2-uv+v^2)(u-v)(u^2+uv+v^2)$

Part C:

If we want to factor $x^6-1$ completely, we can just see that x to the sixth power is just $x^6$ and 1 to the sixth power is just 1. Hence, x can substitute for <em>u </em>and 1 can substitute for v.
